MATUR-ITY CALENDAR:

Specification of Letters Patent. Patented July 11,1922,

Application filed September 22, 1921. Serial 503398.

To all whom it may concern Be it known that l, JAMEs M. SroU'r, a citizen of the United States, residing at Seattle, county of King, and State or Washington, have invented a new and useful lillaturity Calendar; and I do hereby declare that the following is a full, clear, and exact specification, such as will enable others skilled. in the art to which it appertains to make and use the same.

The invention is a device for instantly determining the date upon which a note for any given number of days is due, or by reading backwards the date upon which a note which is due upon a certain date was written.

The object of the invention is to provide a device for determining what day of the month or year is a given number of days from any other day.

A further object of the invention is to assist a person figuring the interest on a note for a given number of days to determine just what day of the month the note will fall due.

A still further object is to provide a device which will enable a person figuring the interest of a note to determine whether or not the note ialls due on a holiday, or a Sunday.

\Vith these ends in view the invention embodies two circular discs, one smaller than the other, and mounted upon it, having three hundred sixty-five numbers equally spaced around its outer edge, and the larger disc also having three hundred sixty-five spaces numbered with the days of the months to match with the spaces of the smaller disc.

Other features and advantages of the invention will appear from the :r'ollowing description taken in connection with the drawings, wherein Figure l is a general view looking on the face of device.

Figure 2 is a cross-section on the centerline.

Figure 3 is side elevation showing the device as it would be used on a persons desk.

In the drawing I have shown my device mounted upon a board 1 by a pin 2 so that the disc 3 may be easily rotated by turning it with the knobs l. The larger disc 5 is fixedly mounted upon. the board 1 and around its outer edge are twelve spaces 6 in which the names of the months of the year may be placed. Just inside of these spaces is a circular space 7 which is equally divided into three hundred sixty-live spaces and numbered according .to the number of days in each month. Around the outside of this space are a number of small holes 8 in which the pins 9 with red heads 10 may be placed to indicate holidays, and Sundays.

Around the circumference of the smaller disc 3 is also a space 11 which is divided into three hundred and sixty-five equal spaces and which arenumbered with the numbers from one to three hundred and sixty-five. At certain intervals some of the numbers may be enlarged as shown in the circles 12 to make it easy to find the time of maturity for the most common notes. At the space on the small disc where the numeral 365 occurs the large arrow 13 may be placed.

It will be understood that any other changes in the construction can be made without departing from the spirit of the invention. One of such changes may be in the use of the two discs by themselves without mounting them upon a back, another may be in the use of one knob instead of two, another may be in the use of a segment containing only a few numbers instead of I the entire three hundred and sixty-five for the small disc, and still another may be in the means for calling attention to the holidays, and Sundays.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

l. A maturity calendar of the class de scribed embodying a disc, spaces around the outside of the disc in which the names of the months of the year appear, other spaces on the disc in which the days of the months appear, a smaller disc mounted upon the larger one, spaces around the circumference of the smaller disc, numerals in rotation in the spaces, some of these numerals repeated in larger type towards the center of the disc and opposite their respective spaces, an arrow at the numeral 865, knobs mounted on the smaller disc for rotating the disc, a pivot in the center of both discs holding them together, upon which the smaller disc is freely mounted as it rotates on it, holes opposite the days of the month in the large disc and pins which may be inserted in these holes, opposite the Saturdays, Sundays and holes, opposite the Saturdays, Sundays and holidays during the year to designate these days so that they may readily be detected, a smaller disc mounted. upon the larger one, numerals "From one to three hundred sixtyfivc on the outer edge of the smaller disc, a pin for holding the two discs together upon which the smaller disc is free to rotate, and a button by which the small disc may be rotated mounted upon the small disc.
